Installation for controlling a hydraulic installation with a plurality of receivers operating in parallel

A control system for controlling a hydraulic installation with a plurality of hydraulic actuators operating in parallel, comprising:

• a pump configured to pump hydraulic liquid;
• a pressure and flow regulator configured to regulate a pressure and a flowrate of the hydraulic liquid pumped by the pump;
• a plurality of conversion units, each of the plurality of conversion units configured to generate a respective pressure value and a respective flow rate value corresponding to respective control positions of corresponding control units for each of the hydraulic actuators;
• a plurality of distributors, each of the plurality of distributors associated with a respective hydraulic actuator of the plurality of hydraulic actuators and configured to supply the respective hydraulic actuator with the hydraulic fluid according to the respective pressure value and the respective flow rate value;
• a plurality of operating mode switches, each of the plurality of operating mode switches associated with a respective distributor of the plurality of distributors and configured to switch the respective distributor to a flow rate sharing mode and a mode without flow rate sharing;
• and
• a flow rate value counter configured to provide an operating mode control signal to the plurality of operating mode switches to switch the plurality of distributors to the flow rate sharing mode when at least two of the hydraulic actuators of the plurality of hydraulic actuators are activated, and to the mode without flow rate sharing when only one of the hydraulic actuators of the plurality of hydraulic actuators is activated;
• an adder configured to receive and to sum the generated respective flow rate values from each of the conversion units and to generate a flow rate regulation signal corresponding to the sum of all of the generated respective flow rate values;
• and
• a selector configured to receive the pressure values from each of the conversion units and to generate a maximal pressure signal corresponding to a highest received pressure value,
• wherein the pump is controlled in the flow rate sharing mode by the flow rate regulation signal and by the maximal pressure signal.
